ALU Positions the 7750-SR as a DPI based Mobile Application Assurance Gateway

    
Alcatel-Lucent published a new, very detailed, application note (here), presenting its 7750 Service Router (known by many as an access router for fixed networks) as a mobile gateway, with DPI capabilities and PCRF control.

This is direct competition to Cisco's ASR-5000 "inline services" (here) and Ericsson's SSR (here).

The note focuses on the merits of using DPI ("L4-L7 DPI") in a mobile service and presenting the 7750 as a PCEF working in conjunction with ALU's 5780 PCRF (covered here) and a mobile gateway supporting "Mobile Application Assurance (AA)".

"Mobile AA leverages MG-ISM hardware capability to identify different network applications by comparing traffic patterns extracted from real-time, stateful traffic inspection of traffic payload against a library of digital signatures, which is kept locally on the Alcatel-Lucent 7750 SR Mobile Gateway. Once a particular network application is identified, the MG-ISM can promptly perform additional actions in accordance with policies that are locally configured on the Alcatel-Lucent 7750 SR Mobile Gateway".

  1. As you said that Mobile AA leverages MG-ISM hardware capability to identify different network applications by comparing traffic patterns extracted from real-time.If this is the case then its a great achievement.
